You will receive a pack of 6 or 12 threaded magnets with black rubber coating, including threaded magnets with bolts, M6 spring washers, M6 flat washers, and M6 nuts. The neodymium magnet base is rubber coated to protect the magnet from damage, avoid scratching painted surfaces, and restrict the magnet from sliding on slippery surfaces. POWERFUL MAGNET MOUNTING BASE: The rubber-coated round base is 1.69 inches (43mm) in diameter and houses 6 neodymium magnets with 22 pounds of vertical magnetic pull against a steel surface. Convenient for outdoor use: These vertical neodymium disk magnets feature 3 layers of corrosion-resistant coating on the surface to protect accessories, and the outer rubber coating is waterproof, allowing for long-term outdoor use. Multifunctional use: M6 external thread studs can be screwed directly into threaded holes of the mounting surface or passed through holes and secured with washers and nuts to connect various hardware components. Ideal for cameras, light bars, display panels, automation equipment, tools, and machinery.
